Description

本開示は、映像を表示する映像表示部と、映像表示部から発する拡散光を複数回反射させ、かつ透過することで異なる空間上に再結像させる空中結像光学系と、空中結像光学系により拡散光が再結像される地点を見る観察者の視点位置情報を取得する視点位置情報取得部と、空中結像光学系の端点及び観察者の眼を結ぶ直線と、観察者の眼から正面の空中結像光学系に到達する直線とがなす角度に応じて、映像表示部からの映像を制御する表示制御処理部とを備えることを特徴とする。 The present disclosure discloses an image display unit that displays an image, an aerial imaging optical system that reflects diffused light emitted from the image display unit multiple times and re-images them in different spaces by transmitting them, and aerial imaging optics. The viewpoint position information acquisition unit that acquires the viewpoint position information of the observer who sees the point where the diffused light is re-imaged by the system, the straight line connecting the end points of the aerial imaging optical system and the observer's eyes, and the observer's eyes. It is characterized by including a display control processing unit that controls an image from an image display unit according to an angle formed by a straight line reaching the aerial imaging optical system in front of the image .
